1. Field of the Invention
The present invention relates in general to a collapsible keyboard that can be folded into a reduced size, facilitating transport.
2. Description of the Related Art
Generally, characters and symbols are input into a computer via a keyboard. Other input equipment such as mouse pointers or light pens fail to offer input speed and ease to match the keyboard. Therefore, the popularity of keyboards remains universal.
A conventional keyboard has a keyboard base, a key base and a plurality of keys. The key base is mounted on the keyboard base, while the keys are mounted on the key base. The user inputs data into the computer by typing the keys of the keyboard. Operation of the computer using the keyboard is easy and fast. Conventional keyboards are, however, too long to allow easy transport.
An object of the present invention is to provide a collapsible keyboard that can be folded into a reduced size, facilitating transport.
The keyboard of the present invention includes a keyboard base, at least one hinge, a key base, at least one fixed hinge, at least one movable hinge and a plurality of keys. The keyboard base has a plurality of first sections. The hinge connects the plurality of first sections so that the first sections are rotatable with respect to each other. The key base has a plurality of second sections provided on the first sections. The fixed hinge connects the second hinges so that the second sections are rotatable with respect to each other. The movable hinge connects one of the first sections and one of the second sections. The keys are provided on the second sections.
The keyboard in use has a longitudinal size equal to that of a conventional keyboard to comply with user habits. When the keyboard is not in use, the user can fold the keyboard so that the keyboard has a reduced size and easily carried.
The present invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
Now referring to
It is noted that the keyboard of the present invention has two halves, which are the same (symmetrical). For easy description, only the right half of the keyboard is introduced.
Referring back to
When the keyboard is in use, the keyboard is open and has a longitudinal size equal to that of a conventional keyboard to comply with user habits, as shown in FIG. 1. To fold the keyboard, the user simultaneously rotates the keyboard in directions A, B, C, D until the sections of the keyboard base contact with each other. As shown in
In the first and second embodiments, the section 26 or 26′ of the key base has an end connected to a fixed hinge and the other end connected to a movable hinge. As well, both ends of the section 26 or 26′ are connected to movable hinges. Referring to
To fold the keyboard, the user simultaneously rotates the keyboard in directions A, B, C, D until the sections of the key base and keyboard base contact with each other. As shown in
It is understood that the pivots 971 and 973 can be replaced with each other. That is, the pivot 973 having the gap 974 is disposed in the groove 83, and the pivot 971 is connected to the section 66 of the key base. Such an arrangement also works.
In conclusion, the present invention provides a collapsible keyboard. The keyboard in use has a longitudinal size equal to that of a conventional keyboard to comply with user habits. When the keyboard is not in use, the user can fold the keyboard so that the keyboard has a reduced size and is easily carried.
While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
